Title: Process for controlling gelation and cure of unsaturated resins
Inventor: HECK HENRY G
IPC: C08F4/40
Filed: 1983-08-03
Abstract: A process for controlling the gelation and cure rate of unsaturated resins useful for thermosettable compositions and laminates. A small amount of an enolizable beta-diketone such as 2,4-pentadione added to a vinyl ester of a polyglycidyl ether of a polyhydric compound, an unsaturated polyester or a mixture thereof contributes toward the control of the rates. Admixed with the enolizable beta-diketone and unsaturated resin is a peroxide selected from ketone peroxides, tertiary hydroperoxides or peroxyesters, and a redox reactive metal salt soluble in the curable resin such as cobalt naphthenate. The unsaturated resins have a pH greater than 5.7 measured as a 10 percent methanol solution. The mixture is maintained at a temperature less than 54oC to extend the nongelled state and then raised above 54oC to achieve acceleration of the cure rate.

Title: Construction and applications of polyproteins
Inventor: TOTH MATTHEW J
IPC: C07K19/00
Filed: 1987-02-26
Abstract: A method for constructing polyproteins which can perform multiple sequential activities. A DNA sequences is constructed using genetic engineering techniques to insert sequences encoding the desired proteins into a plasmid, in the correct order, following a single promoter element and before a single stop codon. The reading frames of the mRNA sequences are phased so that a polyprotein with the desired activities, in the required order, is produced. Modified polyproteins can be produced by inserting or substituting amino acids into the mRNA sequence to create spaces between the individual proteins, to increase the stability of the total polyprotein, to change the spatial orientation of the individual proteins relative to each other and their substrates, and to modify the activity of the individual proteins.

Inventor: DORSEY GEORGE F
IPC: C09J175/04
Filed: 1990-06-27
Abstract: A thermosetting mixture for use as an adhesive, as well as other applications, that is substantially nonmutagenic. This mixture is based upon a thermosetting resin selected from polyurethane and epoxy resins, using an improved curing agent that does not contain mutagenic components. Specifically, the curing agent is a multi-mixture of substituted alkylanilines produced by an improved process. These alkylanilines are formed by condensation of at least two alkylanilines with a formaldehyde in an acid solution. Upon purification, at least three aromatic diamines are formed that are used for the curing agent with the polyurethane and epoxy resins. Pot life, green strength and ultimate strength are comparable to adhesives of the prior art that contain mutagenic constituents. Although several dialines are described, the preferred curing agents are formed using 2,6-diethylaniline (DEA) and 2,6-diisopropylaniline (DIPA), where the mole % of DEA and DIPA is 38-48 and 62-52, respectively. Curing agents within the preferred range have been designated as 'Asilamine 4852' and 'Asilamine 4555'.

Patent WO-9111285-A1 (WO)
Title: Weld repairable combustor
Inventor: FAWLEY ROBERT W
IPC: B23K1/00
Filed: 1991-01-10
Abstract: Combustors of gas turbine engines in which components are brazed to the combustor are not easily repairable by conventional welding because the brazed joint includes a melting point depressant which may not only cause the joint to be brittle but also the melting point of the joint to be near or below the temperatures required for welding. These problems are solved by a relatively simple and inexpensive process for producing a weld repairable combustor which includes using (20) a brazing powder mix comprising a metal powder compatible with the metals of the combustor and the article to be brazed to the combustor, and suitable melting point depressant in powder form, heating (60) the brazing powder mix to a first temperature sufficient to cause the brazing powder mix to become molten, and finally heating (70) the brazing powder mix at a second temperature for a sufficient time to cause the melting point depressant to substantially diffuse away from the brazed area. The resulting combustor formed by this process can be repaired by welding (100) when cracks or other discontinuities requiring a weld repair are situated near or at the brazed joint, and this process avoids the expensive requirement of redesign of the combustor to a welded combustor configuration which would require major tooling, equipment and processing changes.

Title: Area displacement device for molten metal ladle
Inventor: BAI SHEN HUM
IPC: B22D41/04
Filed: 1991-09-03
Abstract: An open-top, heat resistant container (10), such as a molten metal ladle, having a block (30) rigidly attached to the ladle (10) and partly submerged into the surface (22) of the molten metal (20) in the container or ladle (10) for reducing a major portion of the exposed surface (22) of the molten metal (20) in the container (10). The block (30) may be vertically adjustable for varying the amount of immersion into the molten metal (20) when a predetermined amount of molten metal retained in the container (10) has been reached by flow over a weir edge (13) of the container or ladle (10). A fraction of a centimeter difference in the level of molten metal (20) in the container (10), multiplied by the exposed area (22) of the molten metal (20) in the container (10) can amount to a kilogram difference in the molten metal (20) measured by the tilt and weir (13) of the container or ladle (10). Thus, the less exposed area of the surface in the container (10), the more repeatable the measured amount of molten metal (20) can be poured from the container (10). The ladle (10) is mechanically moveable from immersion in a tank (T) of molten metal (20) to a position above the tank (T) for overflow of molten metal (20) over the weir edge (13) and/or tilting of the container (10) to a predetermined angle to retain a measured amount of molten metal (20), and lastly pouring that measured amount into a mold, then starting the cycle over again.

Title: Peg-held connector
Inventor: MOSQUERA RENE AUGUSTO
IPC: H01R12/58
Filed: 1991-10-15
Abstract: A connector is described, of the type that has pegs for insertion in holes of a circuit board to securely hold the connector to the board, wherein the pegs can be easily installed, and they assure secure holding despite variations in circuit board thickness and moderate tolerances in the diameters of the circuit board holes. Each of the pegs (41, Fig. 4) has a peg body (60) with an axis (62), and a plurality of ribs (71-73) projecting radially outwardly form the periphery of the body. The pegs are constructed of material of lower hardness than the material of the circuit board, so the interference fit between the pegs and circuit board results in flattening of the tips of the ribs and/or shaving of the tips of the ribs. Each peg has a slot (66) extending from the periphery of the peg body to near the axis of the peg body, and a pair of the ribs lie on opposite sides of the slot, so radially-inward pressure on the ribs causes the slot to close slightly and allow the ribs to move radially inwardly. The slots of adjacent pegs are oriented so they are turned 90° from each other to reduce the insertion force and the possibility of peg breakage.
